WHMIS and Safe Chemical Handling in Cleaning Operations
If your business uses cleaning chemicals — or if you hire a cleaning company that does — WHMIS compliance isn't optional. It's a legal requirement across Canada, including right here in Newfoundland.
Yet many business owners and facility managers aren't fully clear on what WHMIS actually requires, or what their responsibilities are when it comes to the cleaning products used in their workplace. This post breaks it down plainly.
What is WHMIS?
WHMIS stands for Workplace Hazardous Materials Information System. It's Canada's national standard for communicating the hazards of chemical products used in the workplace. First introduced in 1988 and updated in 2015 to align with international standards, WHMIS 2015 is now the current framework in force across all Canadian provinces and territories including Newfoundland and Labrador.
WHMIS applies to any workplace where hazardous products are handled, used, stored, or disposed of — which includes virtually every commercial facility that uses professional cleaning chemicals.
What makes a cleaning product "hazardous" under WHMIS?
Many common cleaning products fall under WHMIS regulations, including:
- Disinfectants and sanitizers containing bleach or quaternary ammonium compounds
- Floor strippers and degreasers
- Descaling agents used in restroom cleaning
- Window cleaning solutions containing ammonia
- Solvent-based cleaners
If a product meets the criteria for a hazardous product under WHMIS, it must come with a compliant Safety Data Sheet (SDS) and proper labels — regardless of whether it's purchased by a cleaning company or by your business directly.
The three pillars of WHMIS compliance
1. Labels Every hazardous product must have a WHMIS-compliant label that includes the product name, hazard pictograms, signal word (Danger or Warning), hazard statements, and precautionary statements. Labels must be in both English and French and must remain legible and intact at all times.
2. Safety Data Sheets (SDS) An SDS is a detailed document that outlines a product's chemical properties, health hazards, safe handling procedures, storage requirements, and emergency response information. Every hazardous cleaning product used in your workplace must have a current SDS that is readily accessible to all employees who may be exposed to it.
3. Worker education and training All workers who work with or may be exposed to hazardous products must receive WHMIS training. This includes understanding how to read labels and SDS documents, knowing the hazards of the products they work with, and understanding safe handling and emergency procedures.
What are your responsibilities as a business owner?
If you manage a commercial facility in Newfoundland, your WHMIS obligations depend on whether you handle cleaning chemicals yourself or outsource cleaning to a professional company.
If your staff handle cleaning chemicals:
- Ensure all products have compliant labels and current SDS documents on file
- Provide WHMIS training to any employee who handles or is exposed to hazardous cleaning products
- Store chemicals safely and in accordance with SDS instructions
- Conduct regular workplace inspections to ensure compliance
If you hire a professional cleaning company:
- Your cleaning contractor is responsible for the WHMIS compliance of their own staff and the products they bring into your facility
- You should confirm that your cleaning provider is WHMIS compliant before signing any contract
- You are still responsible for ensuring that any cleaning products you supply or store on site are properly labelled and have accessible SDS documents
Common WHMIS violations in cleaning operations
Despite being well-established legislation, WHMIS violations in cleaning operations are surprisingly common. The most frequent issues include:
- Chemicals stored in unlabelled or incorrectly labelled containers
- Outdated or missing SDS documents
- Mixing incompatible chemicals — a particularly dangerous practice that can produce toxic fumes
- Staff using cleaning products without adequate training or protective equipment
- No clear emergency procedure in the event of chemical exposure or spill
Any of these can result in workplace injuries, regulatory fines, and significant liability for your business.
The case for eco-friendly cleaning products
One of the practical advantages of switching to eco-friendly, non-toxic cleaning products is that many fall outside WHMIS hazardous product classifications entirely — simplifying your compliance obligations considerably. Products made from biodegradable, plant-based ingredients are less likely to require the same level of labelling, storage controls, and training as conventional industrial cleaning chemicals.
This is one of the reasons Spurview Cleaners uses environmentally responsible products across all of our commercial cleaning operations — safer for our team, simpler to manage compliantly, and better for the clients and spaces we work in.
How to check if your cleaning provider is WHMIS compliant
When evaluating a commercial cleaning company in Newfoundland, ask these questions directly:
- Are your staff trained in WHMIS 2015?
- Do you carry SDS documents for all products you use on site?
- Can you provide a list of the cleaning products you use?
- How do you handle chemical spills or exposure incidents?
A professional, reputable cleaning company should answer all of these confidently and without hesitation.
